The biggest difference between flexible OLED and foldable OLED will be the cover window material. In terms of price competitiveness, various Colorless Poly Imide (CPI) are superior to suppliers, but in the end, the cover window market is expected to depend on which material Samsung Electronics and Apple choose.
Corona 19 and Huawei’s US sanctions negatively affected the OLED market for smartphones, but it was a plus with Apple’s strong sales of iphone 12.
Although Samsung Display’s rigid OLED line is expected to decrease due to a decrease in Huawei’s volume due to the US production, demand for rigid OLEDs is expected to increase as demand for laptops, monitors and tablet PCs is increasing. To respond to this, investment in rigid OLED lines in A4 is also being reviewed. This year’s notebook OLED panel is expected to come out with more than 10 different model product lines, and Apple’s OLED production for iPad is scheduled to start from 2022, so demand for middle and large-sized OLED panels is expected to increase.
Total shipments of AMOLED in 2020 were aggregated to 575.78 million units. This is an increase of 20.41 million units compared to the 557.46 million units shipped in 2019.

In response to 8K LCD TV quality disputes that LG Electronics compared and exhibited at IFA2019, Samsung Electronics raised the problem of burning of OLED TVs.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often found as under-cabinet luminaires or in decorative articles. But also in the automotive industry the demand for light strips is enormous. Customized strips with additional functionalities play an increasingly important role, especially in the area of innovative car designs.
Recently, due to the trade dispute between the US and China, a large portion of the budget planned by the Chinese government is flowing into the display industry while the semiconductor industry, which is one of intensive investment promotion industries, foreshadows difficulties. In the display industry, the focus is on OLED, which is a cutting-edge technology, and most of the investment is in the 6G line, a mobile product production line. This year has already been made at Visionox and Tianma on the 6G line, and BOE and CSOT will be invested further this year.

Since Royole introduced ‘FlexPai’, a foldable OLED phone, Samsung Electronics and Huawei have also launched Foldable OLED phones, attracting great interest from the industry and the public.
The biggest change of the foldable OLED phone currently being commercialized or under preparation is that the cover window of the glass material used in the existing flexible OLED has been changed to colorless PI material.
As Korean OLED panel makers do not have a lot of investment, the OLED equipment industry is in a low-demand season. When Chinese OLED panel makers confirm the order status of equipment orders in 2019, orders are being made centering on equipment and module line equipment required for new technologies rather than new lines.
Although Samsung Electronics and Apple’s OLED smartphone market are stalled, Chinese smartphone makers are gradually increasing their use of OLEDs based on the huge smartphone market in China. As a result, BOE and Chinese panel makers have aggressively established a Gen6n flexible OLED plant, which is driving the OLED industry.
While LG Display is recording poor performance in first quarter of this year, it is going to strengthen its competitive edge in OLED display, which is its main business. Because it is expected that Chinese LCD will continue to make inroads into supplies this year, Samsung Display is planning to bring about results through high-value OLEDs that are highly profitable.
BOE is going to start construction of its fourth 6th generation flexible OLED plant soon. It is planning to invest a total of 46.5 billion yuan (approximately 7.9 trillion won) to have a monthly production capacity of 48,000 sheets. Although the display market is slumping and demand for flexible OLEDs for smartphones is falling short of expectations, it is speeding up aggressive investments and expanding production capacity.
The Chinese companies’ volume offensive raised concerns that the OLED industry, following liquid crystal displays, could face oversupply problems. Analysts say that while South Korean display manufacturers’ performance in the first quarter has deteriorated due to a sharp drop in prices of LCD panels, even OLEDs, which are seen as new growth engines, could be on the verge of oversupply in the near future.
Following LCD panels, there are predictions that oversupply can become a reality for OLED panels.
Concerns are growing as South Korean companies plan to grow OLEDs into new “cash cow” instead of LCDs that China has taken the lead.
OLED light emitting materials market is gradually increasing as Chinese companies enter OLED panel market led by Samsung Display and LG Display.
